Fire control emergency indicator

Abstract

The invention relates to a fire control emergency indicator which comprises a stainless steel plastic spraying frame, a side light incidence type LED backlight source, a nickel-cadmium rechargeable battery, a transparent flame-resisting glass fiber reinforced plastic mirror surface, an anti-explosion audible and visual alarm and a control circuit board. A transparent flame-resisting glass fiber reinforced plastic mirror surface fixing clamping groove is formed in the stainless steel plastic spraying frame, and the transparent flame-resisting glass fiber reinforced plastic mirror surface is fixedly mounted in the fixing clamping groove. The nickel-cadmium rechargeable battery, the control circuit board and the anti-explosion audible and visual alarm are all arranged in an inner cavity of the stainless steel plastic spraying frame. The side light incidence type LED backlight source comprises an LED module and a light guide plate assembly. The light guide plate assembly is inserted into the transparent flame-resisting glass fiber reinforced plastic mirror surface in a parallel manner. The LED module is arranged on the light incidence side of the light guide plate assembly. The side light incidence type LED backlight source, the anti-explosion audible and visual alarm and the nickel-cadmium rechargeable battery are all electrically connected with the control circuit board. Indicating characters and patterns are etched on the transparent flame-resisting glass fiber reinforced plastic mirror surface. The fire control emergency indicator is convenient to mount and use, achieves energy saving and emission reducing and has a good fire control emergency indicating effect.

Description

technical field [0001] The invention belongs to the technical field of fire emergency safety indicator devices, and in particular relates to a fire emergency indicator board. Background technique [0002] In some public places, such as commercial office buildings, teaching buildings, shopping malls and hospitals, etc., fire emergency signs for indicating safety exits are generally installed in fire exits. Such as fire, earthquake and other situations to help people find the exit smoothly, is an important facility to ensure personal safety. In the existing common signs, they usually work around the clock, and the display brightness is constant, which not only increases the power consumption, but also shortens the working life of the signs, which is incompatible with the background of the era of vigorously advocating green and low carbon. In addition, the direction indicators mostly use LED light strips for static display, which fails to play a good indicating role. Therefor...

In the existing common signs, they usually work around the clock, and the display brightness is constant, which not only increases the power consumption, but also shortens the working life of the signs, which is incompatible with the era background of vigorously advocating green and low carbon

In addition, the direction indicators mostly use LED light strips for static display, which fails to play a good indicating role.
